Caterpillar original Mechanical Fuel Injector 0R-8465 Injectors Nozzle Replacement for OEM 3114 C3116 3406B Engine E325B Excavator Industrial Sprayer original new injector

The Caterpillar 3116 fuel injector 0R-8465 is a high-performance diesel fuel injection component engineered to OEM Caterpillar specifications, serving as a direct-fit replacement for CAT 3116 and 3116B series diesel engines operating across excavators, wheel loaders, articulated trucks, marine vessels, and stationary generator sets. This injector delivers precisely metered and atomized diesel fuel directly into the combustion chamber at controlled timing intervals and pressures, ensuring accurate fuel delivery for stable combustion performance under severe industrial conditions.

Constructed with precision manufacturing at micron-level tolerances, the 0R-8465 injector provides heat resistance for continuous operation in mining, construction, and high ambient temperature environments, while specialized metallurgy offers corrosion resistance against sulfur, water, and fuel degradation. The injection cycle begins when fuel pressure builds within the injector body; once the opening pressure threshold is reached, the nozzle valve lifts and atomized fuel passes through calibrated nozzle holes, creating microscopic fuel droplets that maximize combustion efficiency.

Compatible with multiple cross references including 127-8228, 107-1233, 4P-2233, OR-4103, OR-4370, 127-8216, 127-8230, 162-0212, 0R-8473, 0R-8479, 0R-8684, and 101-8673, this injector reduces fuel consumption, lowers exhaust emissions, improves horsepower output, and extends overall engine service life across demanding B2B applications.
